San Jose, CA Parking Rules: Commercial Vehicle Restrictions (2026)

Commercial-vehicle parking in the unincorporated county is governed by the County's Stopping, Standing and Parking ordinance (Title B, Division B12, Chapter III) together with the California Vehicle Code. Under the County's framework, commercial vehicles with a gross-weight rating in excess of 10,000 pounds may not park in residential areas; parking of large commercial vehicles is permitted on public streets in industrial areas. The ordinance also establishes commercial loading zones marked by curbs painted yellow with a sign at each end, where stopping is limited to loading or unloading of freight and the default effective hours are 9:00 a.m. to 6:00 p.m. unless otherwise posted (the relevant loading-zone provisions are in Division B12, Chapter III). Routine 'no-parking' sign restrictions, weight-limited roads, and posted truck routes can further restrict where commercial vehicles may stand or park. The general 72-hour limit on continuous parking applies to commercial vehicles as well, so a truck or trailer left at the curb for 72 or more consecutive hours may be removed by the Sheriff or CHP. Operators should also check the Zoning Ordinance limits on commercial activity and vehicle storage in residential districts (Chapter 4.20), since storing fleet or work trucks at a home can independently violate zoning even where a single overnight stay would not.
